Struct Label 

pub struct Label { /* private fields */ }

Represents a diagnostic label.

A label is a source span and optional diagnostic text that should be laid out next to the source snippet.

Implementations

impl Label

pub fn at<R>(range: R) -> Self

where Range<usize>: From<R>,

Construct a label for the given range of bytes, expressible as any type which can be converted to a Range<usize>, e.g. [miette::SourceSpan].

pub fn point<L>(at: usize, label: L) -> Self

where Cow<'static, str>: From<L>,

Construct a label which points to a specific offset in the source file.

pub fn new<R, L>(range: R, label: L) -> Self

where Range<usize>: From<R>, Cow<'static, str>: From<L>,

Construct a label from the given source range and diagnostic text.

pub fn label(&self) -> Option<&str>

Returns the diagnostic text, the actual “label”, for this label.

Trait Implementations

impl Clone for Label

fn clone(&self) -> Label

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Label

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Label> for LabeledSpan

fn from(label: Label) -> LabeledSpan

Converts to this type from the input type.

impl From<Label> for SourceSpan

fn from(label: Label) -> Self

Converts to this type from the input type.

impl PartialEq for Label

fn eq(&self, other: &Label) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
